Elephant nose intelligence

I dont think they use electrical impulses. I think is a vocal communication above our hearing. I bet Matt, slip, Rtr, richter, or many other poeple could help ya on that. But dolphins come close to body mass/brain size compared to human brains. Another intelligent mammal. The elephant nose brain is LARGER then humans. Cool tidbit huh?
 
brain size vs. body weight does not neccisarily mean something is smart or not smart.

example- two humans who have the same size brain (20 pounds), one is skinny and weighs 100 pounds (20% brain) and the other is 1000 pounds (2% brain). Now does this mean that the skinny person is going to be smarter than the overweight one?


I said before, most likely the brain size is directly related to the amount of senses it uses. Many mice have brain size vs. body weight almost identical to humans.

brain weight in vertebrates does not in general appear to increase linearly with body weight, so that heavy vertebrates have proportionally smaller brains than light vertebrates, and many small mammals have, in terms of these simple ratios, relatively larger brains than that of humans. . .

I'll totally confuse the conversation. Could I put an elephant nose in my Oscar tank?

I forgot to mention that was a very interesting article

Slip: very true.


However, It uses the brain size for the electrical pulses as well as comminication and social interaction.
 
I was watching a show a couple nights ago on Mako sharks.

Apparently they are one of the smartest fishes, and most likely the smartest shark in the world. They were showing how the Makos learn and remember.


Just found another good quote

comparative studies across species indicate the brain size is not necessarily a good predictor of perceptual or cognitive abilities. Brain size increases with body size. A cow’s brain, for example, is much larger than a human’s brain, but no one suggests cows are smarter than humans. For more on the relationship between brain size and body size, see the Developmental Structure in Brain Evolution, published in the journal, Behavioral and Brain Sciences. In addition, this Bryn Mawr comparative neuroanatomy site helps to visualize the relationship between body size and brain size.

Scientists agree that it is not the size of the brain that predicts intelligence, but the size of the neocortex, which is the upper region of the cerebral cortex of the brain. For more on the brain and the cerebral cortex, see Neuroscience for Kids. The neocortex is the region of the brain that is involved in most complex brain functions such as memory, perceptual awareness, language and consciousness. Only mammals have a neocortex; reptiles, amphibians, and fish do not. Scientists commonly agree that self-awareness, often measured by a “mirror test,” is exclusive to higher primates, such as humans and great apes (although a recent study of dolphins indicates that they react to a mirror image of themselves).

to answer Undertow's question, yes, that is a form of communication. Not quite as sophisticated as dolphins and whales (the warm-blooded variety), but still more complex than even a dog or cat, if I am remembering correctly. These fish react to the impulses that the human body gives off, as well as pheromones that we produce, and this is so sensitive that they can differentiate between two different people, even if they are the same gender, body mass, and genetics. My mother's fish can tell her hand from mine, and reacts accordingly. He/she will just look at my hand, but will swim right up to hers and caress it, like it wants to be touching her. It's really amazing, because it's more than just recognizing by sight, like most fish, but also unique electrical impulses that we produce without even realizing it.

I'm not saying the fish is self-aware, but they are aware, at least...

Your right Slip about bodymass/brain size.
You fail to mention:

1.) how much of that brain do they use?

Cows and mice uses a VERY small portion. HUmans use 20 percent.


you forget to mention that ELEPHANT noses uses more of that brain because of the function of the electrical organ. They need ALOt more o2 to the brain so they can use it more (as said in the scientific article).

Didnt it say it uses 60 percent?
 
ive never seen any documented proof on what percentage of the brain animals (including humans) use. I believe its just estimates.


The article says elephant noses brains use 60% of the O2 they take in, but it doesnt say what percentage of their brain their using.
